NuvohlaAir and Surface Purifier, an innovative and disruptive patented technology that responds to the current and future global need for environmental hygiene.

The new range of purifying and disinfecting devices effectively generate and expand neutral hydroxyl radicals (OH) to inactivate up to 99.99% of pathogens and contaminants in the air and on surfaces.

This technology is called active because it expands its properties throughout the environment and does not only act on the air passing through the device.

It complies with the exposure limits against chemical agents adopted by the National Institute of Safety and Health (INSS).

These parameters include ozone (<0.05ppm) and hydrogen peroxide (<1ppm or <0.1mg/m3) emissions.

The OH technology has been tested in independent laboratories and more than complies with both limits.

Also, the oxidizing agent OH, qualified as a “natural detergent” due to its ability to clean the atmosphere, neutralizes more than 2,500 different compounds such as carbon dioxide or methane, the main causes of the greenhouse effect.

The hydroxyl radical is produced in nature by the combination of the sun’s ultraviolet rays with ozone in the troposphere and also by the reactions caused by the ozone present in the environment on the vegetable oils (terpenes) that evaporate from plants.


By means of Advanced Oxidation Processes (AOP) produced by hydroxyl radicals (OH) it is achieved:

  • Inactivates up to 99.99% of pathogenic microorganisms (viruses and bacteria).
  • Improve air quality by reducing Volatile Organic Compounds (VOCs) and suspended particulate matter (PM).
  • Eliminate odors.


The high effectiveness of the hydroxyl radical is due to the fact that its oxidation potential is among the highest.

Its great oxidizing power is complemented by the chain effect it produces, and it releases more Reactive Oxygen Species (ROS), generating more

Oxygen Reactive Species (ROS), thus generating a wave of purifying agents that spreads through the atmosphere.

Nuvohla – Air and Surface Purifier


The purifying power of OH technology has been tested in several studies on viruses, bacteria, volatile organic compounds, odors and particulate matter.



Viruses are the most transmissible environmental pathogen due to their microscopic size and high volatility.

In all surface tests that have been performed, hydroxyl radicals have inactivated 92 to 99% of viruses.

between 92 and 99% of enveloped and non-enveloped viruses in both wet and dry environments.

In air, the results are expected to be better because the hydroxyl radical can affect the pathogen over its entire surface.

The efficacy on untested viruses will be similar to that on tested viruses because their morphological structure is similar.

Therefore, the results for Covid-19, whose morphological structure is similar to that of Respiratory Syncytial Virus (RSV), would show an efficacy of between 92 and 99%.

In addition to these tests, others were performed on Bactilus Subtilis, Staphylococcus Aureus, Pseudomonas Aeruginosa and Escherichia Coli bacteria showing similar efficacy.

Several field tests have even been carried out in hospitals and schools showing that it inactivates and prevents the appearance of mold caused by excess humidity.


VOCs and PMs

Air quality is mainly determined by the concentration of Volatile Organic Compounds (VOCs) and microscopic suspended particles (PM).

VOCs are carbon-based chemical compounds that may contain fluorine, chlorine, bromine or sulfur, all of which are harmful to health. PM, on the other hand, can seriously affect the respiratory system.

Hydroxyl radicals (OH-) mineralize VOCs and transform them into compounds that are completely harmless to humans and nature.

PM particles are also affected by these radicals by converting them into heavier compounds that fall to the ground.

heavier compounds that fall to the ground, thus reducing air pollution.



These are molecules that escape from their liquid or solid state and pass into the air. They are usually carbon-based and may contain nitrogen and/or hydrogen.

In the same way that they act on VOCs, hydroxyl radicals make the main odor indicators disappear.


  • Hospitals and Clinics
  • Laboratories
  • Veterinary Clinics
  • Schools and Institutes
  • Training Centers
  • Universities
  • Means of transportation
  • Corporate offices
  • Stores
  • Domestic use
  • Food industry


It should be noted that within all sectors an environment free of pathogens is required, as well as with good air quality and without unpleasant odors.

So, although only a few applications are specified in each sector, the effect of NuvohlaAir and Surface Purifier in each application will help to improve the air and surfaces of these sites.

Protect yourself and take care of yourself with NuvohlaAir and Surface Purifier.
